No! This is the #1 roaming trap. Bermuda is NOT part of the EU, UK, or US domestic plans (and often excluded from "Caribbean" plans). Most home carriers (like AT&T, Verizon, T-Mobile, or UK's Vodafone/O2) will charge you their highest "Rest of World" international "Day Pass" rates (e.g., $10-$15 per day). A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper.
